tachment for water closets, Serial No. 603,696,

co-pending herewith, I have described and claimed a water closetattachment of the charactor to which this invention refers, saidattachme-nt comprising an operating mechanism 5 and means for fasteningit onto the bowl of the water closet or bidet.

The operating mechanism comprises a water delivery arm which isrotatable about its own axis with respect to a support therefor, whichis, in its turn, rotatable about a substantially vertical axis. Saidmechanism also comprises a system of valves controlling the supply ofcleansing fluid to said arm support and delivery arm and a single memberfor actuating both 535 said arm support and said valves, the arrangementbeing such that a continuous movement of said actuating member in onedirection from its normally inoperative to its operative position, willfirst bring the delivery arm to position and then will operate the valveor valves to cause cleansing fluid to flow to and through said arm.

An arrangement of the type indicated, entailing as it does the use ofseveral parts mov- 3;) ing in the presence of water under pressure, re-

quires considerable care in its manufacture and also requires frequentinspections and adjustments, in order to prevent leakages which arebound to develop after a certain period of use.

I have found in practice that the difficulty of making and maintainingall joints water-tight constitutes a serious drawback to the adoptionfor general use of a sanitary device of the character to which thisinvention refers. The water supplied by the average city system isgenerally under a considerable pressure, and even small leakages are,therefore, likely to become seriously objectionable. I have also foundthat due 5:3 to the great variety of closet bowls in use it is difficultto produce an attachment which will be usable in all cases, or at least,it is diflicult to produce an attachment which can be readily installedwithout the expenditure of considerable time and labor, in order toinsure the proper position of the fluid delivery arm with respect to thecenter of the bowl.

The primary object of this invention is to provide a sanitary attachmentof the character specified, in which no valves or rotatable parts areemployed in the path of the cleansing fluid between its source of supplyand the point of delivery.

Another object of the invention is to provide, in a sanitary attachmentof the character specified, comprising a fluid delivery arm movable froma normally inoperative to an operative position, a tubular connectiondirectly connecting the fluid delivery arm to the source ofsupply, saidconnection being of such a nature as to permit at any time a freemovement of said arm from one of its extreme positions to the other.

A further object of the invention is to provide, in a device of thecharacter specified, comprising a fluid delivery arm movable between twoposil" tions, a flexible compressible tubular connection between saidarm and a source of fluid supply, and simple means for controlling theflow of fluid through said connection.

A still further object is to provide a sanitary water closet attachmentof a novel and improved type, said attachment comprising a minimumnumber of parts enclosed in a relatively shallow casing or frame,adapted to be mounted directly under the water closet seat.

An additional object is to provide an arrange ment of extreme simplicityin which the fluid delivery arm is directly connected to the source offluid supply without the interposition of valves or other moving partsand in which a single angular movement of said arm about its pivotalsupport is suflicient to bring the arm from its normally inoperative toits operative position.

Other objects and advantages of the present invention will more fullyappear as the description proceeds and will be set forth and claimed inthe appended claims.

My invention is illustrated by way of example in the accompanyingdrawings in which:

As stated in the premises, the novel features of my invention includeimprovements in the operating mechanism proper, as well as improvementsin the manner of mounting the device in position. The improvements inthe operating mechanism are directed mainly towards the production of anextremely simple and absolutely reliable device where a continuous anddirect passage is provided between the source of fluid supply and thepoint of delivery, so as to avoid the possibility of leaks developing atintermediate points.

The improvements in the manner of mounting the device in position areintended mainly to obviate the difficulties now encountered in applyingsanitary devices to water closets of diiferent designs, and to provide anovel type of enclosure and support for the operating mechanism adaptedto be attached directly under the water closet seat.

The basic principle of operation employed in the device forming thesubject of my co-pending application above referred to; namely, anoperating cycle whereby the fluid delivery arm is brought to positionbefore the fluid delivery is started, has also been employed in thepresent case, because such an operating cycle constitutes an essentialcondition for the proper functioning of this class of sanitary devices.In fact, where the movement of the fluid delivery arm from itsinoperative to its operative position is effected simultaneously withthe movement of the valve controlling the fluid flow to a position ofdelivery from a position of non-delivery, the valve generally begins tobe partly open while the arm is still moving towards its operativeposition, so that the cleansing fluid is likely to issue from thedelivery arm before its proper position has been reached.

However, while, in a broad sense, the principle of operation has beenretained, the mechanism itself has been simplified to the point where aminimum number of parts is employed. This reacts to the advantage ofboth the operation of the device and its cost of production, as will beclearly explained in the description which follows.

In order to avoid the difliculties engendered by the necessity ofmeeting conditions arising from the use of water closets of varioussizes and designs, I have conceived the idea of attaching my devicedirectly to the under side of the closet seat. Such a manner of mountingthe device greatly simplifies the problem of applying it in the properposition, because the only precaution that has to be used is to makesure that the nozzle at the end of the delivery arm will remaincentrally located with respect to the bowl. Such an arrangement alsomakes it possible to adopt a standard type of seat already equipped withthe sanitary device attached thereto in its proper position and tosimply substitute the unitary structure thus obtained for the ordinaryseat when the device is to be applied onto a. water closet.

Referring to the drawings, 10 designates a toilet bowl of usualconstruction, formed with a rim 11, surrounding the bowl cavity 12, andhaving a rear extension 13 carrying hinge bolts 14, 15, by means ofwhich the seat 16 is attached to the bowl. The lower surface 17 of theseat 16 is provided with rubber spacing feet 18, resting upon the edgeof the rim 11, causing a clearance 19 to remain between the top of thebowl and the underside of the seat.

The casing or frame carrying the fluid delivery arm and. operating partsof the mechanism, shown at 20, consists of a relatively shallow,open-top structure, extending under and across the rear portion of theseat within clearance space 19, said structure being attached to theseat in any suitable manner, for instance, by means of screws insertedthrough openings 21.

The front part of the casing or frame is preferably formed with a lip22, at one end of which is pivotally mounted at 23 the fluid deliveryarm 24. When the fluid delivery arm is in its inoperative position,shown in Fig. 4, it extends transversely of the seat within the spaceintervening between lip 22 and the underside 17 of the seat. The pivotalsupport 23 of said arm is slightly inclined forward, as shown in Figs.5, 6, 8, 9,

so that when the fluid delivery arm is angularly V displaced about saidpivotal support to its operative position, shown in Figs. 7, 8, 9, itwill be slightly inclined downwardly so as to cause its nozzle 25 toremain vertically spaced a suitable distance from the top 26 of theseat.

It will be observed from Fig. 7 that when the fluid delivery armoccupies its operative position, said arm is at an angle to the centrallongitudinal line of the closet bowl, but the nozzle 25, carried by theouter end thereof, remains set in said central longitudinal plane.Furthermore, by looking at Figs. 8 and 9, it will be observed that thenozzle is directed upwardly and is preferably inclined towards the rear,so as to produce a fluid jet 2'7, which will strike the body of theoccupant of the seat tangentially or at a slight angle to the surfacethereof. A. fluid jet thus directed will clean the surface efficientlyand without splashing and due to its velocity will also carry awayparticles of foreign matter adhering to said surface.

An arm 28 extends inwardly from the pivot end 23 of delivery arm 24through a passage 29 provided in the front wall 30 of frame 20. To theend of said 28 is attached a spring 31, which is attached at the otherend to a fixed point 32, and which tends at all times to move thedelivery arm from its inoperative position, shown in Fig. 4, to itsoperative position shown in Fig. 7.

However, said delivery arm is normally retained in its inoperativeposition against the action of spring 31 by a lever 33, carried by theoperating shaft 34, said lever 33 having a slot 35 (see Fig. 7) throughwhich passes a link 36, pivotally connected at 37 to a lug 38, laterallyloo extending from delivery arm 24. The outer end of link 36 is providedwith a rounded or spherical head 39, which abuts against the outersurface of lever 33, and which forms therewith a sort of universaljoint, permitting slight angular displacements of said link 36 withrespect to said lever 3-3.

The retaining action of lever 33 upon head 39 of link 36- is exerted byvirtue of the action of a spring 40, urging shaft 34 in a clockwisedirection with respect to Figs. 5, 6, 8, 9, to its normal position shownin Figs. 4, 5, 6. Said spring 40 is connected to the inner end 41 ofshaft 34, while the outer end 42 of said shaft projects through andextends from casing or frame 20, said shaft 34 being supported bybearings 43, 44, integral with said frame.

At the outer end 42, said shaft carries a for wardly extending operatinglever 45 which, when depressed, will cause shaft 34 to rotate in acounterclockwise direction with respect to Figs. 5, 6, 8, 9, against theaction of spring 40.

When such a movement of shaft 34 takes place, lever 33 moving forward,makes it possible for link 36 to move towards the inside of the bowl,and, therefore, makes it possible for spring 31 to cause the angularmovement of fluid delivery arm 24 from its inoperative to its operativeposition. It will, of course, be understood that spring 40 is strongenough to overcome the action of spring 31 when lever 45 is released, sothat when this is done, shaft 34 will return to its normal position andlever 33 will pull back the fluid delivery arm by hearing against head39 of link 36.

The cleansing fluid, which is usually water coming from the water supplysystem, is supplied to the fluid delivery arm by a flexible tubularconnection 46, attached to a lug 47 laterally projecting from said armat a point in proximity to its pivotal support 23. Said flexible tubularcon nection preferably consists of a compressible rubber tube, or atleast includes a compressible section 48, which is normally flattened orpinched by the end 49 of a lever 50, said lever being pivotally mountedat 51, and being urged to compress the tubular connection by the actionof a spring 52 bearing against its arm 53. Said tubular connectionenters the casing 20 through an opening provided at 54, through the rearwall 55 of said casing and is attached to the fluid source of supply inany suitable manner.

Due to the clamping or pinching action of part 49 of lever 50, section43 of flexible connection 46 is normally flattened so as to positivelyobstruct the passage of the fluid beyond the point against which end 49bears.

Operating shaft 34 carries a cam 56, against which bears a lug 57projecting from arm 53 of lever 50, the action of said cam being to tiltsaid lever 50, so as to cause its end 49 to release the pressure exertedagainst tubular connection 46, when after a certain amount of rotationof said shaft 34, the fluid delivery arm has reached its operativeposition. It will be understood that cam 56 will only start to cause thereleasing action of lever 50 after the fluid delivery arm has reachedits operative position, in order to insure a condition whereby thecleansing jet issuing from nozzle 25 will be directed to the properspot.

In order to define the point at which the fluid delivery arm will stop,an adjusting rod 58, passing through a bearing 59 and provided withadjusting nuts 60, is preferably attached to the outer end of arm 28.Nuts 60 are, of course, ad-

justable along rod 58, so as to determine the extent of the angularmovement of the fluid delivery arm, which will stop when nuts 60 come torest against bearing 59.

Slot 35 in lever 33 extends sufliciently to permit the movement ofrotation of operating shaft 34 to continue for a while after the fluiddelivery arm has come to a stop and during said period of additionalrotation of said shaft 34, the action of cam 56 against lever 50 willtake place.

By virtue of this arrangement, after the fluid delivery arm has beenbrought to position the pressure exerted against the tubular connection45 is released and the cleansing fluid will issue in the form of a jet2? from nozzle 25. As soon as lever 45 is released by the occupant ofthe seat, spring 40 will automaticflly cause all the parts to return totheir normal position, shown in Fig. 4, overcoming the action of bothspring 31 and spring 52, the various movements taking place in thereverse order, that is, the supply of cleansing fluid to the nozzlebeing cut off before the fluid delivery arm begins to return to itsnormally inoperative position.

In the construction shown, where lever 33 and link 36 are caused toproject above the level of the under surface of the seat, the seat willhave to be provided with a suitable cavity or cavities, such as 61,supplying the clearance space necessary for the operation of thesemoving parts.

In this case it is desirable, in practice, to supply both the sanitaryattachment and the seat as a single unit and, therefore, the casing 20is shown formed integral with hinge members 62, 63,

adapted for attachment to hinge bolts 14, 15, in j the usual manner.This, however, does not exclude the possibility of so modifying theconstruction of the device that it may not be necessary to providecavities in the under side of the seat, so as to make it possible toattach the device 3 to any existing seat. In such a case, it will alsobe unnecessary to provide the device with hinge members, since it willbe possible to utilize the hinge members already attached to the seat.

It is obvious that if desired, cam 56 can be so shaped that the pinchingaction exerted by end 49 of lever 50 against the tubular connection 46will be released gradually so as to regulate the amount of cleansingfluid which will be allowed to reach the fluid delivery arm. This isespecially l important when nozzle 25 is made suitable for theattachment of a rubber hose carrying at its other end a nozzle suitablefor internal treatment by douches or enemas.

While flexible connection 46 may consist throughout of a length ofrubber tubing having a round section, I prefer to make its section 48,subject to compression of end 49 of lever 50, with a normally oval orflat section, as shown in Fig. 11, its passage 64 being in the form of anarrow slit which, of itself, tends to obstruct or impede the passage ofthe cleansing fluid therethrough. Such an arrangement makes it easierfor lever 50 to totally prevent the flow of liquid through said passageand also prevents the tendency of the rubber to crack, which developswhen a round rubber tube is frequently flattened by the action of apinching or clamping member.

The water pressure in an ordinary water supply system is usually fairlyhigh, so that when the pressure exerted by end 49 against section 48 isreleased, the water will automatically cause said section to expand,permitting its flow therethrough. It is, of course, quite possible tomake the tubular connection proper of round rubber tubing and to providethe same at the proper point with oval or flat section 48, also made ofrubber.

In apparatus of the character to which this invention refers it isfrequently desirable to provide means for heating the water delivered atthe nozzle. This is especially desirable when no source of warm or hotwater supply is available and when the device is also made usable forinternal treatment.

In order to take care of these requirements I have, therefore, shown anarrangement which can be adopted in connection with my device, saidarrangement being illustrated in semi-diagrammatic form in Figs. 1, 3,i, 6, 7, 9. In the same it will be seen that water from the supplysystem reaches a receptacle through pipe 66 and then reaches tubularconnection i6, which is attached to the outlet of said receptacle at 57.Receptacle 65 is provided with suitable means for heating the waterpassing therethrough, for instance, electric heatin means (not shown),the terminals of which cs, 69, are inserted through the circuit of wire70 of an electric supply system. Said wire 70 is attached to terminal68, while the branch wire 71, originating at terminal 60, is attached toa contact member 72 and the other line wire 73 is attached to a contactmember 74, said contact members 72, 74, being placed directly aboveoperating shaft 34. A hand-operable switch 75 is inserted in one of theline wires 73, providing means whereby the occupant of the seat maycause the water issuing from the nozzle to be cold or warm, as he maywish.

The electric circuit is normally interrupted at 72-74, but connectionbetween said two contact members is established by a contact drum 76,mounted on shaft 34, as soon as said shaft starts to rotate whenpressure is exerted against lever 45.

In other words, the electric circuit of the heating means is normallyinterrupted at two points; namely, switch. 75 and contact members 72-74.Said c suit is closed at 7274 every time shaft 34 is operated, but theheating means will not be energized unless switch 75 has previously beenset in its circuit closing position.

It will be understood that the heating arrangement within the receptacle65 may be of any suitable type; for instance, the water may be caused topass through coils interposed between pipe 66 and outlet 67, said coilsbeing exposed to the action of electric heating elements energized bythe current passing through the circuit. Another uitable arrangementwould be to have the water issue through pipe 66 within receptacle 65and to equip this receptacle with electric heaters of the immersiontype.

The rubber tubing is preferably provided with reinforcing spiral wireshields at the points of bending, as indicated, for instance, in thedrawings at 77.

It will be observed that no valves or other moving parts are interposedin the path of the cleansing fluid from its source of supply to thefluid delivery arm, so that no leakages are likely to take place.

It will also be observed that if any water should manage to leak throughsection 1-3, when COL.J pressed, the leakage would drip through nozzle25 and would be discharged directly into the closet bowl withoutsplashing on. or causing any damage to the floor or any other part ofthe bathroom. The avoidance of all valves and other parts movable underthe necessity oi maintaining water-tight connections also results in anextreme simplification of the mechanism as a whole, so that its cost ofproduction is accordingly very much reduced.

Several parts of the mechanism so far described are movable in avertical plane and, therefore, make it necessary to provide cavities inthe underside of the seat, as explained. In the majority of cases it isdesirable to apply the apparatus directly onto the underside of anexisting seat, and this should be done with an expenditure of a minimumquantity of labor.

I have, therefore, devised another type of mechanism also embodying myinvention where all the parts are movable in a horizontal plane so thattr e shallow chamber formed by the casing is sufficient of itself tohouse the same at all times.

Such an improved type of mechanism is illustrated in Figs. l2, 13 of thedrawings. In the same 78 designates a relatively shallow casing, whichcan be red onto the underside of the seat by means of screws at 79, 30,forming therewith a shallow chamber 81. The operating member is a cranklever 82, mounted on a vertical pivot 83, said lever having an operatingarm 8-1 projecting sidewise or" the seat to which fluid delivery arm 86is carried by a bracket 87, mounted on an inclined pivot 88, and made tocommunicate with an inlet tube 89, to which is connected the deliveryend 90 of a rubber tube 91, attached at the other end to a source offluid supply such as, for instance, the water supply system. Said rubbertube enters the shallow casing at th rear at 92 and is di wardlyextending lug 99, which projects directf'.

ly in the path of arm of crank lever 82. Crank lever 82 is normally heldin the position shown in full lines in Fig. 12 by a spring 100, attachedat one end to a fixed point 101 and at the other end to arm 85 at 102. aradial extension 103, the outer end of which is formed with acylindrical lug 104, having a slot 105 through which passes a rod 106.Said rod is attached at 107 to arm 85 and has at its other end a head108, causing a spring 109 to j exert pressure against a washer 110,bearing against the surface of cylindrical lug 104. Said rod 106 alsocarries a collar 111, bearing against the opposite side of lug 104.

When arm 84 of the operating lever is moved in a counterclockwisedirection from the position shown in full lines in Fig. 12 to thepositlon shown in dotted lines at 84', the fluid delivery arm is causedby rod 106 to move to its operative position, shown in dotted lines at36, its movement being effected by virtue of the pressure exerted bywasher 110 against cylindrical lug 104.

When the fluid delivery arm reaches its operative position it isrestrained from going any Bracket 87 is formed with L].-

fartherbecause bracket 8 strikes edge 112 -:Of rib portion .113ofca'sing 78. At this point arm :85 of operating lever 82 is about tostrike against lug 1990f arm 9'7, and upon continued movement of arm 84in the same direction, arm 85 will actually bear against lug 99 andcause a certain angular displacement of crank lever 95 in a clockwisedirection, thereby relieving the pressure exerted by end 93 of arm 1914against the rubberttube. This free movement of the operating lever ismade possible by the yielding connection provided by spring 109 betweenrod 166 and 193 of bracket 87, as will be understood.

The mechanism operates, therefore, in a manner analogous to thatpreviously described, the fluid delivery arm being first brought toposition and cleansing fluid being then permitted to flow through therubber tube leading to the fluid de livery .arm. As soon as pressureagainst arm 84 is relieved, spring 100 will automatically return theoperating lever to its normalposition, collar lll bearing againstcylindricallug 1-04 and in its turn causing the fluid delivery arm toresume its normal position shown. At the same time spring 98 will alsoautomatically return lever 95 to its normal position, where end .93 ofarm 94 checks the flow of fluid through tube 91.

It is obvious that casing 7.8 may be made with or without a hingeattachment for the seat, being without said hinge attachment when it isdesigned for use in connection with a seat already mounted in positionon its own hinges.

From the foregoing it will be seen that I pro vide an entirely new typeof sanitary attachment for closets and bidets, which is free from themany objectionable featurescharacterizing other kindred devicesheretofore in use.

It is obvious that the various constructional details of my device mayvary from those shown without departure from the inventive idea; thedrawings, therefore, should be understood as being intended forillustrative purposes only and not in a limiting sense.

I, accordingly, reserve the right to carry my invention into practice inall those ways and manners which may enter, fairly, into the scope ofthe appended claims.
